I have only had my iphone4 a week and disappointingly have already used up 80% of my fair use download policy. I have downloaded apps (obviously) namely sky news and sports, ibooks, ebay/paypal and facebook, plus I have been playing Cat Physics. I didn't think I had 'gone mad' so was disappointed to receive a message from T Mobile that I had used up so much of my monthly download (I have 750mb). I expect that my experimenting with watching sky news live has used up a fair bit, although I have not watched it for more than a minute or so a couple of times. Does listening to radio use a lot? Any tips / help appreciated. Am loving my iphone despite this. Thanks!
